Injecting logger, weld

I am trying to replace standard logger initialization by some injection

1-st.

I was trying to use weld weld logging in stateless bean/webservices

@Stateless
@WebService
public class EchoSSL {

    @Inject
    private Logger log;


    public EchoSSL() {
    }

    public String echo(String msg) {
        log.debug("Log test");
        return "Echoing: " + msg;
    }
}

But it not working for me.. i get java.lang.reflect.InvocationTargetException

What is missed ?

2-nd

than I try this tutorial that is referenced to this - Custom Injections

But it also dosen`t help.

maven dependencies -

<dependencies>
        <dependency>
            <groupId>org.jboss.weld</groupId>
            <artifactId>weld-logger</artifactId>
            <version>1.0.0-CR2</version>
        </dependency>
        <dependency>
            <groupId>开发者_C百科org.jboss.weld</groupId>
            <artifactId>weld-extensions</artifactId>
            <version>1.0.0.Alpha1</version>
        </dependency>
        <dependency>
            <groupId>org.jboss.weld</groupId>
            <artifactId>weld-api</artifactId>
            <version>1.0-CR2</version>
        </dependency>
        <dependency>

            <version>1.0.1-CR2</version>
        </dependency>
    </dependencies>

Q1: What is the rule of weld Logger injection in ejb / web services ?

Q2: Could it be wsdl/EJB/WebService issue ?

---

This is my approach:

Add the following dependencies to the pom.xml:

<!-- SL4J API -->
 <dependency>
 <groupId>org.slf4j</groupId>
 <artifactId>slf4j-api</artifactId>
 <version>1.6.0</version>
 </dependency>

 <!-- SLF4J JDK14 Binding  -->
 <dependency>
 <groupId>org.slf4j</groupId>
 <artifactId>slf4j-jdk14</artifactId>
 <version>1.6.0</version>
 </dependency>

 <!-- Injectable Weld-Logger -->
 <dependency>
 <groupId>org.jboss.weld</groupId>
 <artifactId>weld-logger</artifactId>
 <version>1.0.0-CR2</version>
 </dependency>

Inject the Logger and use it as usual:

import javax.inject.Inject;
import org.slf4j.Logger;

public class Example {
  @Inject
  private Logger logger;

  public void exampleFunc() {
    logger.info("Hello Logger!");
  }
}

If you wanna use Log4J instead of the SLF4J-JDK14-binding, i found this page. I tried it, but i couldn't get it to work so i still stick with my own solution.

Make sure your bean is in a bean archive - i.e. that you have META-INF/beans.xml

Apart from the weld extension, which I can't help you with unless you give the whole exception, you can create a producer that @Produces a Logger

---

The default slf4j logger producer is defined in Weld Extensions. You can see how the producer is written here if you wanted to wire up your own without including all of Weld Extensions.

---

in this case I haven`t placed bean.xml in META-INF.
